user1 = "aqa code"
pass1 = "uzair123"
username = input("Enter username: ")
password = input("Enter password: ")
while username != user1:
print("Access denied: username is incorrect try again ")
username = input("Enter username again: ")
if username == user1:
print("access granted")
while password != pass1:
print("Password is still incorrect")
password=input("Enter password again: ")
if password == pass1:
print("Access granted")
while password != pass1:
print("Access denied,Password is incorrect")
password=input("Enter password again: ")
if password == pass1:
print("Access granted")
如何在用户名/ user1中添加.lower(),以便在输入答案时变为不区分大小写?请帮忙。

您可以在返回输入功能时调用.lower
。
username = input("Enter username: ").lower()
password = input("Enter password: ").lower()

添加.lower()
确实是您正在寻找的解决方案,但您可能希望尝试简化一下流程,因此每当您想要修改输入语句时,编辑的位置就会减少。为此,我建议为每个循环创建一个最初为false的变量,并且只在每个循环中获取一次用户输入:
loop_condition = False #initialize loop condition
while not loop_condition: #loop until we say so
value = input("please enter a value: ") #human input
value = value.lower() #convert to lower case for comparison
if value == "password": #test
print("success")
loop_condition = True #loop will terminate when we hit our `while` again
else:
print("fail")
print("rest of program goes here")
在这里,您可以看到我们只调用input()
一次,并且只需要在一个地方将其转换为小写。简单永远是你的朋友。
注意:如果您使用的是python 2.7,请使用raw_input()
